CARBON MONOXIDE (CO) DETECTOR
If you have purchased a MM2350C, MM2350DFC, MM4350C, MM4350DFC, MM9350EC, or MM9350DFEC Model it is equipped with a carbon
monoxide (CO) Detector with an automatic shut-down system.
The CO Detection module monitors for the accumulation of poisonous CO gas found in engine exhaust when the generator is running. If the CO Detector
detects increasing levels of CO gas, it automatically shuts down the engine. CO detector only monitors for carbon monoxide when the engine is running.
Generators are intended to be used outdoors, far from occupied buildings and with the exhaust pointed away from personnel and buildings. However, if misused
and operated in a location that results in the accumulation of CO, like indoors or in a partially enclosed area, CO detector shuts off the engine, notifies the user
of what has happened, and directs the user to take action for safety. The CO Detector is not a substitute for an indoor carbon monoxide alarm.
After a shut-down, a blinking RED light in the CO Detector on the control panel of the generator provides notification that the generator was shut off due to an
accumulating CO hazard. The RED light will blink for at least five minutes after a CO shut-down. Move the generator to an open, outdoor area and point the
exhaust away from people and occupied buildings. Once relocated to a safe area, the generator can be restarted and the proper electrical connections made to
supply electrical power. The RED light will stop blinking automatically upon engine re-start. Evacuate personnel, introduce fresh air, and ventilate the location
where the generator had shut down.
If a CO Detector system fault has occurred and it no longer provides protection, the portable generator is shut down automatically and the YELLOW light will
blink for at least five minutes on the control panel to notify the user of the fault. The CO Detector module can only be diagnosed and repaired by a trained
technician. The generator can be re-started, but may continue to shut down if the fault remains present.
The CO Detector will detect the accumulation of Carbon Monoxide from other fuel burning sources such as engine powered tools or
propane heaters used in the area of operation. For example, if another generator is used and the exhaust is pointed at a CO Detector
equipped generator, CO Detector may initiate a shut-off due to rising CO levels. This is not an error. Hazardous Carbon Monoxide has
been detected. The user must take action to move and re-direct these devices to better dissipate Carbon Monoxide far away from
personnel and occupied buildings.
